and nasa has a near-earth program. it is, i would argue, it is underfunded because of what's at stake here both in the sense of preparedness and dealing with injury and upset. but as to deal with international incidents that might occur. you mentioned the 2002 meteorite over the mediterranean, at the time, the deputy director said if this would have happened over the subcontinent it might have been mistaken for a nuclear explosion in this belligerent stand off between india and pakistan at the time. there are certainly occasions back in the soviet days when the united states and russia mistook natural occurrences for what might have been belligerent events. and so, you have to watch these things. and the nasa near-earth program is important for all of those reasons. as you pointed out, as your other guest pointed out, the energy that's contained in just say small rock, you know, a foot across or a couple of feet across, traveling at these velocities can pack a lot of energy. so when it explodes, it's as if a nuclear ex

we'll bring you nasa's teams tracking this asteroid from jpl in pasadena, california. we have folks at a new york planetarium and we have meteorologist chad myers all joining in to talk about this. so let's begin with tom foreman, because he is sort of our go-to 3-d guy apparently. tell me what this asteroid really looks like. >> you understand what it really looks like, you have to understand where it is. you've been talking about how it is one of the closest encounters we ever had, the closest for this size thing. let's get some reference points on it. manufacture many of us think about the moon as if that is something close to us. it is not that close. it is actually about a quarter million miles away. so what really is close to us, brooke? well, satellites are close. lots of them. this is a scale of where the satellite bands are around our earth. the furthest ones 22,000 miles out there. and where is this thing going to come from? this asteroid will come sweeping out here and go through the satellite band. let me give you a different angle. let's see how close we'r
